Outcomes: The primary outcomes is to determine if NSS is effective at reducing pain in cancer patients undergoing invasive procedures, we will compare mean pain scores during the procedure from the HPRI between the NSS group and the standard care group. We will also compare the difference between ratings of baseline pain and pain during the procedure in the two groups and the rating of pain control during the procedure between the groups. We will also determine if NSS reduces pain more than non-nature based distraction therapy we will compare pain ratings, and the difference in pain ratings from baseline to that during the procedure between the NSS and the music/photo group. Lastly we will determine if NSS reduces affective distress in cancer patients undergoing painful procedures we will compare mean scores from the POMS between the three groups. Secondary outcomes that pertain to all specific aims include vital signs during procedures and salivary cortisol levels. We will also assess overall satisfaction with care, ratings of physicians, ratings of nurses, and attitudes towards CAM interventions using Likert-type scales.
